When I create a pdf it gives me security options including blocking printing. But can I block a pdf I send to someone from being emailed further?

Nevermind. I’ve since learned forwarding cannot be prevented. There is a way to prevent the person receiving the forward from being able to open the pdf, but it is so complex it isn’t worth it.

Blocking printing seems to be circumventable too.
